How to update Domain Service from Entity Data Model?


Hi guys,

So I'm using Entity data model to reflect my database and I generate Domain service from my Entity data model.

I understand that if I have changes in my database, I can just choose "Update Model from Database", but there is no "Update Domain service from Model" option available.

How should maintain my domain service? I'm not going to delete away it and regenerate it whenever there are some changes, right?

I need to know what if

- I add in new table in my database, how should I update from database-->model-->domain service?

- I add in new fields in my table, how should I update from database-->model-->domain service?

AutoGenerateSelectButton="False" ignored when using Domain Service


Crosspost from RIA Services forum: http://forums.silverlight.net/forums/t/196466.aspx

I'm creating a Dynamic Data application in VS2010 and have recently switched to using a Domain Service to give greater control over the data presented to the client. I've noticed that the AutoGenerate<Action>Button attributes on my GridView are being ignored. The presence of the Edit and Delete buttons appear to be contingent on the existence of Update and Delete methods on the partial classes autogenerated in the Domain Service, but i'm not seeing how to control the generation of the Select button. Is there a way to control this from within the Domain Service class?

Trying to set update panel trigger programmatically


 I have a recursive sub that finds a dropdown list and sets up an AsyncPostbackTrigger for an update panel. I have tried calling this sub both from page_init and page_load 

If the dropdownlist is within the update panel, eveything works fine. If the dropdown list is not in the updatepanel I get error

A control with ID 'ddlPersonFilter' could not be found for the trigger in UpdatePanel 'up1'. In both cases the sub does find the dropdown list and executes the code to set up the trigger. Thanks for your help.

    Private Sub SetUpdatePanelTrigger(ByVal oControl As Control)
        For Each ctrl As Control In oControl.Controls
            If TypeOf ctrl Is DropDownList Then
                If CType(ctrl, DropDownList).ID = "ddlPersonFilter" Then
                    Dim thisddl As New DropDownList
                    Dim thistrigger As New AsyncPostBackTrigger
                    thisddl = ctrl
                    thistrigger.EventName = "SelectedIndexChanged"
                    thistrigger.ControlID = thisddl.ID
                    Exit Sub
                End If
                If ctrl.HasControls Then
                End If
            End If

Web Service and Base Class Sub Routines



I have several Web Services that I call using jQuery, they are all <WebMethod()> _    Public Function and return either a boolean or string, depending on the function.

I have some Web Service functions, where I would like to call sub routines I have in my base class, they are Public Sub's.

When I add a call of a sub routine in the Web Service function, I get a blue line that says 'Object reference not set to an instance of an object'.  If I change the sub routine to Public Shared Sub, then the blue line and error go away, but I get other errors from the calls I was successfully making to the base class routines before.

Is there a way to get these two to work together?

SQL Server 2005 Express Edition Service Pack 3 (KB955706) update is successful but repeats installin

  Microsoft SQL Server 2005 Express Edition Service Pack 3 (KB955706) (update 1 of 1) This update seems to be stuck in a loop of installing, each time it successfull installs acccording to automatic updates. Then says it requires installing again straight away. This has been happening for 10 days now. I have tried a manual update from the website rather than automatic updates, no change. Any ideas why? Have posted in Windows update which is where I think the problem lies but they have suggested I post here also.

Update SharePoint List item using UpdateListItem web service with javascript

I'm using the Custom_AddListMenuItems function in a CEWP to add a menu item to each list item to Archive that item. This is achieved by updating a choice field in the item to 'Archived'. I'm trying to do this using the web service UpdateListItem web service to update the item using Javascript, but I can not find the correct code that updates the list item. I'm using this code:     var ctx=currentCtx;     var ciid=currentItemID;     var xmlHttp=null;     if (confirm("Are you sure you want to Archive this item?"))     {         var soapRequest = '<?xml version="1.0" encoding="utf-8"?>'+             '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'+             '    <soap:Body>'+             '        <UpdateListItems xmlns="http://schemas.microsoft.com/sharepoint/soap/">'+         

All data in class properties disappear across WCF service

Hi, I have a class that i share betwee silverlight client and wcf service. I populate properties of the class with real data from the client, to be used in the server. I use debugger to step through the code when the call gets to the server, all the data ara gone and are replaced with null. All DateTime value change to 1/1/1001. But if pass primitive types such as int, string, no problem. This is happening only on one machine, but not on ther machine. Can someone tell me what is going on here? Thanks in advance

Customizing pages with Asp.Net Dynamic Data Domain Service Web Applications?

Hola, It used to be so easy creating new folder under CustomPages with the (Entity/Table name) and copying on it all base default PageTemplates (Details, Insert, Edit, List and ListDetails) and you will get access to those pages only for the specific table (this was the default automatic behavior of the Dynamic Data framework) When it comes to be using Asp.Net Dynamic Data Domain Service Web Applications it seems that we need to learn a new way of doing this because it is just simply different and you got a lot of errors when compiling your application if you do this the old way? What might be the new way, uh? HOW DO WE DO THIS NOW ... I MEAN ... CREATING DEFAULT CUSTOM PAGES FOR SPECIFIC TABLES (Details, Insert, Edit, List and ListDetails) with Asp.Net Dynamic Data Domain Service Web Applications? The problem arises when the definition for your newly created classes is absent from the automatically generated code when you created your domain service !!!!! . If you simply copy the PageTemplates as they are, you got a duplicated error message because the new .designer file (automatically generated) conains the definition of the class you are copying (not the newer one) so even if you rename your .aspx file the result is not what you would normally expect (the .designer class is not regenerated after renaming). The .designer file keeps the domain service definition and if y

Cannot INSERT record using Asp.Net Dynamic Data Domain Service Web Applications

 Hi, I am working on a 'Asp.Net Dynamic Data Domain Service Web Application' project using just 2 tables, FAQ_Categories and FAQs. The FAQs table has a foreign key to the FAQ_Categories. The steps are straight forward. Add a new project (Asp.Net Dynamic Data Domain Service Web Applications) Add folders Model ( for Linq2Sql datacontext), Domain (for the Domain Services class) Add Linq2Slql and add the 2 tables to the designer. Build the project. Add the Domain Service Class to the Domain folder. in the wizard select the DataContext, uncheck the Enable Client & Expose ODate checkbox Check bothe table & their corresponding Enable Editing tables checbox Check the Generate Metadata class Click OK. In Global.asax set Scaffold to true and add the DomainService name. Build and run.   Pages List and Detail are working fine. But if I try to insert a new record, I get the error "FaqId is required" Faq_ID is the primary key in the database table and it is set to Identiy. The Datacontext is correct, it marked the FAQ table with <Global.System.Data.Linq.Mapping.ColumnAttribute(Storage:="_CustomerId", AutoSync:=AutoSync.OnInsert, DbType:="Int NOT NULL IDENTITY", IsPrimaryKey:=true, IsDbGenerated:=true)> _   I tried this using Linq2Sql, Entity Framework, And both in VB and C# with the same result. I am using VS20

User Profile Service - "The specified user or domain group was not found"

Hi there, I had configured the User Profile Service and all was working well (Syncing with AD etc.). However, something has gone wrong. The services still appear to be running; both Forefront Identity Manager services are running, and the services show as 'Started' in Central Administration. The 'My Profile' and 'My Site' options have disappeared though, and browsing to the My Sites page results in an error (Could not load user profile). To make matters much worse, it seems to have also broken the Central Administration site. If I try and go to 'Manage Service Applications' I get another error (The specified user or domain group was not found). This error seems to come up on around half of the pages on the Central Administration site. Looking up the error (abb6b174-0f71-413a-a27a-41cdc87b66d0) in the logs I find this: 09/06/2010 15:35:45.44  w3wp.exe (0x0868)                        0x06A0 SharePoint Portal Server       User Profiles                  cm6y High     User Profile Application Proxy failed to retrieve partitions from User Profile Application: Microsoft.Office.Server.UserProfiles.UserProfileA
